12VAC5-610-580: Septage management; general

Ultimate management of septage generally falls into one of two categories, landfilling or land spreading. Landfilling requires that the septage be stabilized and dewatered to increase solids content nearly fivefold to avoid leaching problems. Land spreading of both stabilized and unstabilized septage is permissible under controlled conditions for agricultural purposes. The preferred methods for septage disposal are disposal in an approved sewage treatment plant or stabilization and subsequent disposal by land application or landfilling in accordance with the Biosolids Use Regulations (12VAC5-585-10 et seq.).
